Condensed-Matter Physics & Materials Science Seminar
"Magnetotransport in Weyl and Dirac Metals"
Presented by Gustavo Monteiro, Stony Brook University
Thursday, December 10, 2015, 1:30 pm — ISB Building, Room 201
Dirac (Weyl) metals are characterized by the linear dispersion of electron quasiparticles, with the Dirac (Weyl) point hidden inside a Fermi surface. In this talk, I will refer to the so-called chiral kinetic theory to describe within the same framework both the negative magnetoresistance caused by the chiral magnetic effect (CME) and quantum oscillations in the magnetoresistance (SdH effect) due to the existence of the Fermi surface in these materials. I will also argue about the role of Fermi arcs and their contribution for the SdH modes. At last, I will discuss the relevance of obtained results to recent measurements on Cd As .
